Back goggle strap broke off within 3 normal wears, no falls/collisions of any kind. The problem is that the strap in back is anchored to the base of the helmet rather than the other direction (towards the crown of the head), so the strap of the goggles always slides up; then, within 3 regular wears, the goggle strap base just slid out and now is lost on some ski slope. I guess you get what you pay for.
